We get a UNKNOWN DATABASE exception because a connection string uses target DB.
runQuery() tries to execute CREATE DATABASE statement within an absent context. We can use multistatement as a workaround to execute CREATE DATABASE query within a system DB context

… target DB.

`runQuery()` tries to execute `CREATE DATABASE` statement within an absent context. We can use multistatement to execute `CREATE DATABASE` query within a `system` DB context

Error connectingjava.sql.SQLException: Connection refused (Connection refused), server ClickHouseNode [uri=http://localhost:8123/test, options={client_name=Test_1}]@630096182

instead of localhost and 8123, you should get the host and port from clickHouseContainer.

        String hostName = clickHouseContainer.getHost();
        Integer port = clickHouseContainer.getFirstMappedPort();


@Container
private ClickHouseContainer clickHouseContainer = new ClickHouseContainer("clickhouse/clickhouse-server:latest")
.withInitScript("./init_clickhouse.sql");;
